' This invention relates particularly'j'ito Referring now more particularlytothe molds adapted for use in connectingfground 'companyingdrawingsin which like-numerals wires to underground' lead-sheathed cables.

Here'toforethe attachment or bonding of a ground wire to '*a cable sheath has been ob- "tained by endeavoring to solder a" strip'iof wire to the lead sheath, but with indiiferent success and, therefore, this invention has as its primary object to provide means for effici enta, gr'ound i fi t e sheathf a And a more specific object of'thi's invention resides in the provision'ofa device read- 7 sheath.

ily detachably connectible with a cable, which simultaneously clamps the ground wire to the'cable sheath and provides a m'old for pouring solder or other like material, around the ground wire to secure the same to'the cable With the above andother objectsineview which will appear as the descriptionproceeds, my invention resides in the novel constructionfcombination and arrangement of parts substantially as hereinafteri'described and more particularly defined byl'the append 'claims, it being understood that Such changes in the precise embodimentof, the herein-disclosed invention may-"be' made as a j 1s connected a flexible chain 21 which is passed come within thescope of-theclaims; In the accompanying- "drawings, I have illustrated one complete example of the physical embodiment of my invention con-' structed according to the best mode I have so far devised for the practical application of the principles thereof, and in which:

Figure 1 is a cross sectional viewthrough 'vdesignate like parts throughout theseveral I -views, the numeral 5 represents acable hav-;

ing an outer lead sheath dand a'plurality of conductor wires 7. insulated froin the lead sheath by insulation 13. A groundwire 9 which is preferably flexible is la'id longitudinallyon the cable and'secured thereto at i a point at whichthe' lead'sheath 6 has been scraped clean, by my improved clamp or bonding mold 10. r

' The clampfior' bonding mold consists of a I -1nember 11 having an arcuatef groove '12 in its under surface, the radius of which is sub- V stanti'ally that'iof the-outside diameter of the cable and from which apair' of arms andlteXtend. Communicatingi with the 'arcuat'e groove 12- is an enlarged inverted cup shaped recess 15,;the upper end of; which "is open, as'at 16, and extending through the end. walls 17 of the recess 15' are aligned 1 Y notches 18 which correspond'to the size of the ground wire9 so as to straddle the same and-securely clamp it to the lead sheath when the bonding moldisgsecured thereto. The arm 13 isapertured, as at 19, to receive'a: screw 20,, to the lowerend of which 'funderlthe cable-and brought. upwardly on ltheotlier side thereof to be inserted in a sl'ot provides 'meansfor drawing. the chain taut 1 to clamp the bonding mold to the cable, as 1 will'bereadily apparent.

Thesolder 24 may'bepoured, 1 through'the'opening 16 in the'mold or may vbeinserted'in any other desired manner. Aft

'l'y modified: form ofmy inventionl adapted t particularly for use in connection with cables of smaller diameters and in this instance the chain 21 is dispensed with and a pair of bonding molds is provided, the upper mold 25 being substantially identical 'to the mold except that its arcuate recess'26 is formed with a smaller radius. The bottom mold- 27 of screws secured in recesses 28 in the outer end of eacharm 29. The arcuate recess 30 of the lower mold is formed with a larger radius than that of the upper mold so asto accommodate a larger diameter cable there different sizes of cable. r

From the. foregoingdescription taken in i connection with the accompanying drawings, it will be readily apparent to those skilled it in-the art to whichan invention of this char- -vidingthe bottom for the opening, and said iacterappertains that I have providedabonding mold which facilitates the connection" of a ground wire to the lead sheath-of ;a ,cable and which is readilydetachably'conneotible Lface-ofthe cable. 1? a l i 6- A m dfor use nfo ming-abe isup a sleeve comprising in combination a 2 body withthe-cable to maintain the ground wire in secure contact with the surface of the cable during its connection: therewith;
